BEER-COOLER.

SPECIFICATION forming part of Letters Patent No. 238,065, dated February 22, 1881.

Application filed March 17, 1880, (No model.)

To alltvhom it may concern:

Beit known that I, STEPHEN G. SPIGER, a

i citizen of the United States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Beer Pumps and Coolers, which improvement is fully set forth in the following specication and accompanying drawings, in which- 1o Figure 1 is a front view of the pump and cooler inclosed in a box the doors whereof are open. Fig. 2 is a transverse section in line a' w, Fig. l.

Similar letters of reference indicate correspending parts in the two gurcs.

My invention consists of apump adapted to force air into a coolingchamber which communicates with a keg or barrel of beer, whereby the beer Will be cooled, and may be made 2o livelywhen required, as will be hereinafter fully set forth.

Referring to the drawings, A represents a box having doors for access to the interior thereof. Within the box is secured an airz 5 pump, B, and a cooling-chamber, C, which communicate With each other by means of a ilexible or other pipe, D 5 and within the box is also located the barrel or keg of beer, which communicates with the chamber C by means of a 3o exible or other pipe, E, attached to said chamber and to the cock a of the keg or barrel.

In order to operate the piston of the pump B the piston-rod B has pivoted to it a bifurcated arm, F, whose upper end is hung on the 3 5 wrist-pin of a crank, G, secured to a shaft, b, which is mounted on uprights or the wall of the box A, and carries a pinion-wheel, c, with which meshes a larger wheel, d, to the outer end of Whose axis is secured a crank or handle,

4o c, for conveniently operating said Wheels, and

consequently the pump.

The cooling-chamber C is closed at all sides, except at places of inlet and outlet or connection with the flexible pipes D E, and has be- 4 5 low it a drip-pan, H, which is supported on the inner walls of the box A, or by other suitable means; and within the chamber is a fan or wheel, J, with wings, blades,vanes, or paddles,

, which is loosely mounted on the walls of said chamber adjacent to the connection of the 5o pipe D.

The door of the box A is properly lined with metal or other material, the lining being preferably of pan form, in order to receive the drippings of the ice and utilize them for drinking purposes, and a proper faucet will be employed for drawing off said drippings.

The operation is as follows Ice is placed on the top of the chamber G, thus cooling the interior of the latter. When itis desired to cool 6o the beer the cock c is closed and the pump B properly operated, thus forcing air into the chamber C under pressure, the air thus being cooled, and by openin g the cock a the cold air immediately exerts its cooling inuence on the beer, the effect whereof is evident. The pressure of air mayA also be utilized for imparting life to the beer when flat, and causing the dispensing of the beer with a suitable head. As the air enters the chamber C it rotates the fan 7o or wheel J, whichagitates the air and causes it to enter the keg or barrel in afresh and lively condition; and as I-obviate the use of the breath of the barkeeper, as often practiced, and foul air from the cellar, it is evident that by 75 my improvement pure and clean air is injected into the keg or barrel. As the ice melts on top of the chamber C it runs down the sides of said chamber into the pan H, (from whence it may be drawn off, if desired,) and as it over- 8o ows it drops into the bottom of the box A, thus serving to cool the air in said box, assisting to cool the outside of. the keg orbarrel, and providing cool air to be pumped into the chamber C.

Suitable check-valves are provided for preventing the return of cold air from. the chamber C to the pump-barrel, or the flowof beer from the keg or barrel to the chamber C.

For convenience of applying or removing 9o the cock f, the part g of the front wall of the box through which said cock is passed is made removable; but I do not consider this essential.

It is evident that my improvement is appli- Vcable for cooling ale and some other iuids.

I am aware that it is not broadlynew to combine au air-pump with a cooling-chamber and inlet and outlet pipes for the purpose of forcing air into a keg or barrel of liquor; also,

that fans have been used in rei'rigerating and air-forcing devices. I do not claim such cou- 5 struotions or applications, broadly.

What I claim is- 1. In combination with the air-pump B and pipes D E, the air-chamber C, having an icereoeptaole formed upon its top and a drip-pan 1o upon its bottom, substantially as set forth.

ing to stir said air for the purpose of freshenl ing it.
